Metallic Solids

Metallic Solids

Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability....

Theory of Metallic Conduction

Theory of Metallic Conduction

The conduction of free electrons inside a conductor is best described by quantum mechanics. However, a classical model makes predictions close to the results of quantum mechanics. It is called the theory of metallic conduction.
In this theory, Newton's second law of motion is used to determine the acceleration of an electron in the presence of an applied electric field. Then, its velocity is expressed via this acceleration.
An electron moves through the crystal, containing positive ions,...

Crystal Field Theory - Octahedral Complexes

Crystal Field Theory
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...

Bonding in Metals

Bonding in Metals

Metallic bonds are formed between two metal atoms. A simplified model to describe metallic bonding has been developed by Paul Drüde called the “Electron Sea Model”.

Atomic Force Microscopy

Atomic Force Microscopy

Atomic force microscopy (AFM) is a type of scanning probe microscopy that can analyze topographic details of various specimens like ceramics, glass, polymers, and biological samples. AFM offers over 1000 times more resolution than the optical imaging system. Images generated from AFM are three-dimensional surface profiles, offering an advantage over the flat, two-dimensional images from other imaging techniques.
The AFM Probe
The probe is regarded as the heart of any AFM setup and comprises the...

Area of Science:

Materials Science
Catalysis
Computational Chemistry

Background:

Understanding catalyst electronic structure is crucial for optimizing catalytic performance.
Single-atom alloys (SAAs) offer tunable electronic properties for catalysis.

Purpose of the Study:

To present a d-d interaction model for Cu-based SAAs.
To correlate electronic structure with catalytic activity, specifically for the water-gas shift reaction.
To investigate anomalous electronic interactions in Mn-doped SAAs.

Main Methods:

Development of a d-d interaction model based on antibonding state position relative to the Fermi level.
Electronic structure calculations (density of states, charge transfer, crystal orbital Hamilton population, wavefunctions) for Hf/Mn-doped SAAs.
Energetic analysis of water dissociation for the water-gas shift reaction.

Main Results:

The d-d interaction model successfully predicts catalytic performance.
Cu-based SAAs with antibonding states near the Fermi level show excellent water dissociation ability.
Mn-doped SAAs exhibit unique behavior with negligible electronic interaction, resembling free atoms, leading to poor catalytic performance.

Conclusions:

The d-d interaction model provides a systematic approach to understanding electronic interactions in Cu-based SAAs.
Catalytic performance in the water-gas shift reaction is strongly linked to the electronic structure, particularly the antibonding state's proximity to the Fermi level.
The anomalous electronic behavior of Mn in SAAs necessitates further investigation.
